So that's the reason. LOL
But it is not some kind of rule, it is just how it feels because when we are without clothes, we feel vulnerable.

I started with CPU rendering, but later managed to get gtx1080 so my computer can render anything in few minutes and I never encountered a situation where GPU would lack memory.
You must be spending all day on rendering such series if it takes 40 minutes for one image.

Considering memory requirement, you can reduce them quite a lot if you rescale textures. Halving their resolution does not affect quality that much (and cannot even be noticed if you are not doing extreme close-ups) but reduces memory consumption more than twice. there are even scripts available that will resample all textures.

Here I would say that 3delight is not that bad if you use it right.
in fact, I am considering to move from Iray to 3delight myself because it is much faster (about 3 minutes for one picture) for complex scenes while picture quality is not much different from what you managed to make using iray.
As the additional benefit, you can turn off shadows what simplifies lighting.
But since I have this very fast video card it is funny that rendering time is pretty same on both engines and sometimes iray even manages to do job faster.

Btw, you did explained your secret what way you use to you push skin of your characters.
